Metastable behavior of Urbach tail states in BaTiO3 across phase transition
Vikash Mishra, Archna Sagdeo, Kamal Warshi +4
The temperature dependent diffuse reflectance spectroscopy measurements were carried out on the polycrystalline samples of BaTiO3 across the tetragonal to cubic structural phase tr…
Comment on Half metallicity along the edge of zigzag boron nitride nanoribbons (Phys. Rev. B 78, 205415 (2008)
Hari Mohan Rai, Rajesh Kumar, Pankaj R. Sagdeo +2
We would like to comment that the prediction of Half-mtallicity in only B edge H-passivated zigzag boron nitride nanoribbons (ZBNNR-BH), by Zheng et al.1, is not correct as their i…
Optical bandgap and bowing parameter for Fe doped LaGaO3
P. R. Sagdeo, Preetam Singh, Hari Mohan Rai +3
The polycrystalline samples of LaGa1-xFexO3 have been prepared by standard solid state reaction route. The phase purity of the prepared samples is confirmed by powder xray diffract…
Role of Metal Nanoparticles on porosification of silicon by metal induced etching (MIE)
Shailendra K. Saxena, Priyanka Yogi, Pooja Yadav +6
Porosification of silicon (Si) by metal induced etching (MIE) process have been studies here to understand the etching mechanism. The etching mechanism has been discussed on the ba…
Half-metallicity in Armchair Boron Nitride Nanoribbons: A First-Principles Study
Hari Mohan Rai, Shailendra K. Saxena, Vikash Mishra +5
Using density functional theory, we predict half-metallicity in edge hydrogenated armchair boron nitride nanoribbons (ABNNRs). The predicted spin polarization is analyzed in detail…
